Sparkbliss, an online dating matchmaker applies “six degrees of separation”. They believe your social network is the key to bringing together individuals of similar interests, backgrounds and values. Each member develops a private network of trusted friends and families who can view his/her profile and make romantic introductions on their behalf. Members have complete control over who they invite into their private network. Some people add as many connections as possible, while others are more conservative. Adding “super connectors,” those people that seem to know everybody maximizes your ability to discover your soul mate.
(The design of their site sure does not want me to use their service…)
